OUTBREAK OF DENGUE FEVER IN LAHORE: STUDY OF RISK FACTORS
AbstractBackground: Dengue fever is a rapidly emerging arthropod born viral disease threatening to becomean international public health problem. Approximately 500,000 people suffer from denguehaemorrhagic fever and dengue shock syndrome with 20,000 deaths annually. Objective of this studywas to look into the risk factors associated with the development of dengue fever. Methods: This crosssectional descriptive study was conducted on patients admitted in various hospitals of Lahore withsuspected Dengue fever. Data was collected on a questionnaire from 109 conveniently selected patients.Results: Mean age of the patients was 34±16.5 years, and majority (80, 73.4%) were male.Seropositivity for dengue was found in 78 (71.5%). The study did not find significant statisticalassociation of seropositivity with demographic variables. However, source of water supply was foundassociated with dengue seropositivity (p=0.002). Conclusion: Source of water is a determinant ofcontracting dengue fever owing to it a breeding media for mosquitoes. All other phenomena associatedwith use of water and sanitation needs to be part of long term control of dengue that will also contributeto controlling other diseases with the same determinants.Keywords: Dengue fever, dengue haemorrhagic fever, dengue shock syndrome, water sources, epidemic
